4344429d3d video: mxsfb: Introduce regulator support
Instead of using a custom binding for retrieving the GPIO that activates the
LCD from devicetree, use a standard regulator.

This approach has the advantage to be more generic.

For example: in the case of a board that has a PMIC supplying the LCD voltage,
the current approach would not work, as it only searches for a GPIO pin.

e3276998da clk: sunxi: rename compatible strings
During the introduction of the Allwinner SoC platforms, sunxi was
initially meant as a generic name for all the variants of the Allwinner
SoC.

It was ok at the time of the support of only the A10 and A13 that
look pretty much the same; but it's beginning to be troublesome with
the future addition of the Allwinner A31 (sun6i) that is quite
different, and would introduce some weird logic, where sunxi would
actually mean in some case sun4i and sun5i but without sun6i...

Moreover, it makes the compatible strings naming scheme not consistent
with other architectures, where usually for this kind of compability, we
just use the oldest SoC name that has this IP, so let's do just this.

====================
The following patchset contains 7 Netfilter/IPVS fixes for 3.9-rc, they are:

* Restrict IPv6 stateless NPT targets to the mangle table. Many users are
  complaining that this target does not work in the nat table, which is the
  wrong table for it, from Florian Westphal.

* Fix possible use before initialization in the netns init path of several
  conntrack protocol trackers (introduced recently while improving conntrack
  netns support), from Gao Feng.

* Fix incorrect initialization of copy_range in nfnetlink_queue, spotted
  by Eric Dumazet during the NFWS2013, patch from myself.

* Fix wrong calculation of next SCTP chunk in IPVS, from Julian Anastasov.

* Remove rcu_read_lock section in IPVS while calling ipv4_update_pmtu
  not required anymore after change introduced in 3.7, again from Julian.

* Fix SYN looping in IPVS state sync if the backup is used a real server
  in DR/TUN modes, this required a new /proc entry to disable the director
  function when acting as backup, also from Julian.

* Remove leftover IP_NF_QUEUE Kconfig after ip_queue removal, noted by
  Paul Bolle.

0c12582fbc ipvs: add backup_only flag to avoid loops
Dmitry Akindinov is reporting for a problem where SYNs are looping
between the master and backup server when the backup server is used as
real server in DR mode and has IPVS rules to function as director.

Even when the backup function is enabled we continue to forward
traffic and schedule new connections when the current master is using
the backup server as real server. While this is not a problem for NAT,
for DR and TUN method the backup server can not determine if a request
comes from client or from director.

To avoid such loops add new sysctl flag backup_only. It can be needed
for DR/TUN setups that do not need backup and director function at the
same time. When the backup function is enabled we stop any forwarding
and pass the traffic to the local stack (real server mode). The flag
disables the director function when the backup function is enabled.

For setups that enable backup function for some virtual services and
director function for other virtual services there should be another
more complex solution to support DR/TUN mode, may be to assign

d52701d39e mfd: ab8500: Kill "reg" property from binding
The ab8500 device is a child of the prcmu device, which is a memory mapped
bus device, whose children are addressable using physical memory addresses,
not using mailboxes, so a mailbox number in the ab8500 node cannot be
parsed by DT. Nothing uses this number, since it was only introduced
as part of the failed attempt to clean up prcmu mailbox handling, and
we can simply remove it.

ab302bb0b8 hwmon: (adt7410) Document ADT7420 support
The adt7410 driver supports the ADT7420, but its documentation file
makes no mention of that. Add this refrence, and a brief a description
of the differences between the ADT7410 and the ADT7420.

6d21a41656 hwmon: (pmbus/ltc2978) Update datasheet links
Links to datasheets are no longer valid. Provide links to product information
instead (which provides links to the datasheets and is hopefully more
persistent).

8fd5e7a2d9 ImgTec Meta architecture changes for v3.9-rc1
This adds core architecture support for Imagination's Meta processor
 cores, followed by some later miscellaneous arch/metag cleanups and
 fixes which I kept separate to ease review:
 
  - Support for basic Meta 1 (ATP) and Meta 2 (HTP) core architecture
  - A few fixes all over, particularly for symbol prefixes
  - A few privilege protection fixes
  - Several cleanups (setup.c includes, split out a lot of metag_ksyms.c)
  - Fix some missing exports
  - Convert hugetlb to use vm_unmapped_area()
  - Copy device tree to non-init memory
  - Provide dma_get_sgtable()
